use Workerman\Connection\TcpConnection;

use Workerman\Timer;

require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker('http://0.0.0.0:6161');

global $offset;

$worker->onWorkerStart = function() {

global $offset;

$offset=0;

};

$worker->onMessage = function(TcpConnection $connection, $data) {

$redis = new Client('redis://127.0.0.1:6379');

$redis->del('key1');

$redis->rPush('key1', 'A');

$redis->rPush('key1', 'B');

$redis->rPush('key1', 'C');

$redis->rPush('key1', 'D');

$redis->lLen('key1', function ($r) {

var_dump($r); // 4

});

};
